Sunny days. Ocean breezes. Sandy shores. Leafy palm trees. Cool jazzy sounds spiked with pop, hip-hop, reggae, soul, calypso, even some street-corner swing, all in the service of positive vibes, spiritual uplift and“don’t worry, be happy”fun. Look beyond those alluring, seductive Surfaces, though, and that’s where the three-dimensional musical depth of the band’s principals truly shine through. The pair have increasingly meshed their individual talents into one impressive whole.
